Density and spatial distribution of the crab Ocypode quadrata (Fabricius, 1787) (Crustacea, Ocypodidae) on three sandy beaches of Espírito Santo, Brazil [PDF]

Biotemas, 2008
The relative density (number of burrows/m2) and spatial distribution of the crab Ocypode quadrata were evaluated on three sandy beaches of Vila Velha-ES: Itaparica, Itapoã and Praia da Costa.

Anthropogenic Disturbance Threatens the Endangered Tufted Ghost Crab, Ocypode cursor

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT The tufted ghost crab, Ocypode cursor, native to the southeastern Mediterranean and subtropical Atlantic Ocean, is a key bioindicator species, providing valuable insights into the health and stability of sandy beach ecosystems through its population dynamics, behaviour and interactions with the environment. Sandy shores along the Mediterranean

Flooding and a complex predator community drive American oystercatcher nest and chick survival in Virginia

The Journal of Wildlife Management, Volume 90, Issue 2, February 2026.
We investigated low American oystercatcher (Haematopus palliatus) productivity in the Virginia barrier islands, which historically supported high oystercatcher reproductive success. We found that chick survival was lower than nest survival, and that management may need to adapt to address evolving threats from coastal flooding and a multi‐guild ...

Latitudinal Variation in the Timing of Nest Predator Activity Is Habitat Specific

Global Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim The goal of this work was to investigate whether the community of avian nest predators shifts from nocturnal to diurnal with changes in latitude. This hypothesis was formulated 70 years ago, under the rationale that longer day length during the bird breeding season at high latitudes increases opportunities for visual predators.

No place to call home: Distribution patterns of the tufted ghost crab, Ocypode cursor, populations in nature reserves, Israel, Eastern Mediterranean

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 34, Issue 3, March 2024.
Abstract The once plentiful population of the tufted ghost crab, Ocypode cursor, a legally protected species, suffered a steep decline along the densely populated Mediterranean coast of Israel. Here we assessed the effects of recreational disturbance on crab populations in three sandy shore nature reserves and adjacent bathing beaches with differing ...

Thermal Ecology of Ocypode quadrata and Pachygrapsus crassipes using Infrared Thermography [PDF]

, 2021
Temperature is crucial to the optimal functioning of most physiological and behavioral processes in animals. For ectothermic crabs that inhabit shorelines, temperature fluctuations and anomalies pose a challenge for maintaining optimal body temperature ...

Variation in the body growth parameters of the ghost crab Ocypode quadrata from morphodynamically distinct sandy beaches

Brazilian Journal of Oceanography
Investigations of patterns of distribution of sandy beach macrofauna show that dissipative beaches tend to concentrate higher richness and biomass at the intertidal zone, as well as better fitness and larger sizes of a species, than reflective beaches ...

Atlantic ghost crabs (Ocypode quadrata) as coastal bioindicators: assessing human impact across the South Atlantic Bight

Frontiers in Ecology and Evolution
Sandy beach ecosystems are increasingly threatened by human activity, making it critical to effectively evaluate their health. While this has often been done using an urbanization index (a tool that quantifies the level of human impact) and a ...
